12 Person Spin Bike Generator System Made for Toyota
|We offer custom group pedal power systems with power monitoring software for your event.
The power from each rider is fed into a power monitoring electrical box which combines the power from each rider and channels it to a 12 Volt battery. The power is routed through battery charge controller to avoid over charging the batteries. Users of this system typically store the energy in battery power packs which convert it from 12 Volts to 110 Volts AC so that it can power up musical equipment, charge cell phones, run blenders for fruit smoothies or drinks, and many more items.The power monitoring software option allows you to monitor the power from each rider and display the data on a standard – large screen display.
The power output per person riding for a one hour period ranges from 0.05 kWH to 0.5kWH. (Children = 0.05 professional athletes = 0.5) So a 10 person system can give you 0.5kWH to 5kWH. There is two ways to display the energy from the riders (1) Strict electrical power measurement (2) Power from the body which is 4 times the amount of the actual electrical measurement. This has caused problems in the past because many bike power meters show the rider the energy from their body which is much higher than the actual electrical measurement.
The reason for the wide difference is is that your body must convert potential energy from muscles to drive pedals which drive a sprocket which drives a chain which drives a rear sprocket which drives a tire which turns the generator through a belt or roller, passes through a length of wire to the battery bank or capacitor. By the time it gets to the battery bank it is 1/4 of what your body spent.
The laptop above shows real time data monitored from the group pedal power system. Click on image to make larger. Persons name or initials, Volts, Amps, Watts, Watt Minutes, Status. And the total power output is shown at the top. This software is completely customizable to include ANY type of graphics , color schemes, logos. Talk to the sales representative for more details. This laptop can easily plug into a large screen display to show everyone how much power is being produced.
